Abstract

The method involves converting potential energy of arbitrary mass carriers at a rate of 9.81 watt second per kilogram meter that is reduced based on specific losses of devices, into electrical energy using a power generator (8). A floating body (1) e.g. ship, of the mass carriers is loaded with heavy materials e.g. rock, and raised in the sea or a storage reservoir e.g. locking chamber. Pivoting movement of the floating body at ebb-tide or during emptying of the storage reservoir by hydraulic or mechanical devices is used to drive the generator for producing current. An independent claim is also included for a device for producing and storing electrical energy.

Description

  • Wagner 1) describes the requirements for a secure power supply. It assumes that the electricity supply is always exactly the same as the electricity demand. Pumped storage power plants make an important contribution to stabilizing the power grids.
  • The known pumped storage power plants consist of two pools, the height as far as possible lie apart. In between is the actual power plant with the turbines, pumps and generators / motors arranged. Should the power plant Supplying electricity, the water is transferred from the upper basin over the Turbines headed into the lower basin. Should the upper basin be filled the way of the water is reversed. The generators will be then used as motors for driving the pumps, the pump the water upwards.
  • The Electricity requirements for the pumping process today usually supply basic power plants in low-demand times. But there are also increasing supply peaks z. B. from wind power to fill the upper basin used. The efficiency of pumped storage power plants is up to 80%. The loss of energy due to the circulation of the Water is provided by the operational advantages of the basic power plants and contributions for short-term security of supply outweighed. The cost of peak load electricity from pumped storage power plants can reach up to 2 EUR per kWh when demand is high.
  • The energy balance of the Federal Republic of Germany 2) has a consumption of pumped storage electricity of 9.1 TWh for the year 2006. Thus, about 1.5% of the total electricity consumption of 614.6 TWh was used to stabilize the grids and increase the short-term security of supply.
  • The Use of renewable energies such as wind energy and or solar power generation is associated with sudden fluctuations (minute reserve), that need to be balanced. Added to this are the natural ones Fluctuations in electricity supply over the course of the day and the seasons. Pumped storage power plants are used in particular around the short-term demand or supply fluctuations for electricity compensate. The demand for power plants of this kind tends to increase. The addition of pumped storage power plants is u. a. also because of Conservation aspects hardly possible.
  • Physical basics
  • The raising or lowering of a mass is associated with the use or the gain of energy. 3) To accelerate a body of mass 1 kg with 1 meter per second is a force to spend:
  • Force of acceleration:
    • 1 N (Newton) = 1 kg × 1 m / s 2
  • At the earth's surface, a body accelerates to the center of the earth at 9.81 m / s 2 . Gravity on a body of mass 1 kg is:
  • Gravity at the Earth's surface:
    • 1 kp (kilopond) = 9.81 N = 1 kg x 9, / 81 m / s 2
  • Becomes the mass of 1 kg raised by 1 m, so is a job to do:
  • Lifting work on the earth's surface:
    • A stroke = 1 kp × 1 m = 9.81 Nm
  • The work done by an electric current is measured in Ws (watt-seconds). Mechanical work and electrical work are equivalent. The following applies: 1 Nm = 1 Ws
  • In order to raise a mass of 1 kg by 1 m with the aid of an electric drive, electrical work must be carried out: 1 kp m = 9.81 N m = 9.81 Ws
  • The The work done to lift the body is a potential one Energy that returns when lowering the body can be won. Lifting a body can do that used for storing electrical energy. In the following Example calculations will simplify lifting 1 kg by 1 m set with 10 Ws.
  • State of the art
  • It is known that the gravity of dammed water masses is used to generate electrical energy and in pumped storage lakes to store electrical energy. The flow characteristic of the water is used to raise or lower large masses with low energy losses. For example, the pumped storage power plant Herdecke 5) stores a working capacity of 590 MWh per filling.
  • It is known that the braking energy of vehicles (trains, cars) is also used during downhill driving to recharge entrained batteries. The Swiss Railways 4) have developed locomotives that convert the braking energy of the trains into electricity and feed it back into the railway network. The aim of these developments was initially to relieve the mechanical brakes during long descents. Meanwhile, the recovery of braking energy and thus the energy savings increasingly gaining in importance. Depending on the type of vehicle can recover between 30 and 70% of the energy used in mountain driving.
  • Problems with the state of the art
  • The increasing use of renewable energy reduces the share Base load electricity from large fossil power plants. There are more and more Times with a surplus supply of electricity. At other times The demand for electricity is higher than the supply. sharpen in the electricity supply must in times of low electricity supply or high electricity demand. The storage capacities for electrical energy are scarce.
  • The Hydropower generation is due to the presence of water tied to suitable height differences. The annex to pumped storage Power plants is very limited.
  • solution
  • The Storage of electrical energy through the "uphill" pump of water is physically based on lifting the mass of the water. Alternatives to the pumped storage power plants result itself, if the storage medium water by any mass carrier z. B. rock is replaced.
  • The Basic equation for the potential energy includes given gravity only the variables: mass and lifting height. Ie. Saving appreciable amounts of energy are great Raise masses as high as possible.
  • Of the Invention is based on the object, methods and devices to develop the gravity to produce and store use electrical energy and capacity to produce as well as storage of electrical energy increase.
  • Hub Power Plant
  • A lifting power plant uses a floating body as a mass carrier on which the lifting work is performed. Lifting power is provided by the tidal stroke 11 of the sea or the damming of water into basins (eg lock chambers).
  • At the Lifting is a part of the buoyancy of the float over turning mechanical or hydraulic equipment into a torque, which drives a power generator. When lowering the float the potential energy of the float is exceeded turning mechanical or hydraulic equipment into a torque, which drives a power generator.
  • The low lifting and lowering speeds of approx. 1 m / h (tidal range) are to raise so that a generator with sufficiently high Speed generated electricity. Hydraulic devices or pumps are suitable for this purpose.
  • drawing 1 shows the principle of a tidal stroke power plant. A float (eg pontoon or ship) which floats at high tide and sinks at low tide drives the power plant.
  • The float is anchored against lateral drifting. Under the float a hydraulic system is installed on the seabed, the piston 2 is lifted at high tide. At the same time flows over the lower inlet valve 4 Water in the lower chamber of the hydraulic cylinder 3 one. When low tide starts, the inlet valve becomes 4 closed and the water by the weight of the float from the lower chamber of the hydraulic cylinder via pressure pipes 5 for driving a turbine 7 pressed. The turbine drives a power generator in a known manner.
  • Alternatively, the hydraulic system can also be designed so that both the buoyancy movement and the lowering movement of the float are used. The upper and lower intake valves 4 are then opened or closed alternatively. The backstops 6 steer the water over the pressure pipes on the turbine. The hydraulic system performs the function of a pump that is driven by the float.
  • Drawing 2 shows a tidal stroke power plant, which is arranged on the float itself. In this case, only the piston stem 2 extended to the seabed and fixed there. On the seabed becomes a solid foundation 13 for receiving the piston shaft 2 generated contact pressure and fixing the piston shaft attached. The hydraulic fluid is passing through the turbine 7 alternately in the upper and lower chambers of the hydraulic cylinder 3 pressed and flows back into the respective opposite cylinder chamber. The turbine is designed to operate in both directions of flow.
  • With tidal range power plants, the following advantages can be achieved:
    Tidal lift Power plants can be used on all coasts where a tidal lift occurs.
  • Large floats z. B. Bulk Freighter 6) have a water displacement up to 360,000 t. If this mass is raised by 5 m twice a day, there is potential energy of 10 MWh / day.
  • The Floats can be reasonably priced Concrete trays are made. Extensive structures and dams, which are necessary for the operation of known tidal power plants, can be omitted.
  • Existing Moorings for ships and pontoons where Tidal lift occurs, can be designed as a lifting power plants become.
  • Hubkraftwerke can be installed in ships and pontoons. On the Seabed then only fixed requirements are needed.
  • Instead of a very large hydraulic system can have several standardized hydraulic units on or on the float be attached.
  • Of the Drive of the power generator can also by mechanical drives (eg winches, racks, pulleys) realized become.
  • Hubspeicher power plant with Fahrzeughub
  • Drawing 3 shows an electrically driven vehicle 17 (eg train or truck) that is a hill 14 loveliness. For this purpose, the vehicle uses the power from the grid 16 , On the descent, the vehicle's gravity drives a power generator 18 that feeds the electricity back into the grid.
  • at Several vehicles (trains, railcars, Vehicle) to vehicle systems. Every single vehicle represents its own "energy package", depending on the electricity supply or electricity demand goes up or down. At the top and at the lower end of the route are stations, on which many vehicles can be parked. In order to Hubspeicher power plants are almost arbitrarily scalable with vehicle stroke.
  • An example calculation illustrates the orders of magnitude of the storable potential energy: a concrete cuboid 17 with the dimensions height = 5 m, width = 2.5 m and length = 10 m includes 125 m 3 which corresponds to a weight of about 360 t. A vehicle of 15 m in length should be sufficient for the concrete cuboid including the electric drive / generator 18 to record. If such a vehicle negotiates a height difference of 500 m, its potential energy is 500 kWh = 0.5 MWh. 100 vehicles can store about 50 MW of electrical energy. The vehicles would each need a "station" with a track length of only about 2,000 m (eg 4 × 500 m) at the upper and lower end of the hub spokes.
  • The following advantages of Hubspeicher power plants with vehicle lift can be achieved:
    The Hubspeicher power plants with vehicle lift can be used on any terrain that has a slope.
  • Stroke memory Power plants with vehicle lift are not due to the presence of water bound. They can also be used in desert regions become.
  • extensive Structures such as dams that are known to operate pumped storage Power plants are required, can be omitted.
  • The Vehicles for the transport of the mass can be technical be very simple, because the speed of the vehicles is very low.
  • It can partially existing track bodies or roads are used for testing.
  • Stroke memory Power plants with vehicle lift can be scaled almost arbitrarily.
  • The Vehicles can also with the help of z. B. winches pulled up and lowered.
  • Hubspeicher power plant with Spindle
  • Drawing 4 illustrates the operation of a Hubspeicher power plant with screw stroke. An electric motor 18 drives a spindle 21 to who the mass carrier 20 raising. When lowering the gravity of the mass carrier drives the spindle in the opposite direction. The spindle drives the power generator 18 which feeds the electricity generated back into the grid.
  • The following Advantages of a Hubspeicher power plant with screw stroke can to be reached:
  • The Hubspeicherwerke with Spindelhub can on any terrain be used.
  • Hubspeicherwerke with Spindelhub have a small footprint and can even under the earth's surface or under buildings be built.
  • The Spindle stroke technology can also be used at the Hub power plants become.
  • Hubspeicher power plant with Seilwindenhub
  • Drawing 5 illustrates the operation of a Hubspeicher power plant with Seilwindenhub. An electric motor 18 drives a winch 24 to who the mass carrier 20 raising. When lowering the gravity of the mass carrier drives the winch in the opposite direction of rotation. The winch drives a power generator 18 to the electricity generated in the network 9 feeds back.
  • The following advantages of a Hubspeicher power plant with Seilwindenhub can be achieved:
    Hubspeicher power plants with Seilwindenhub are independent of the occurrence of water. You can z. B. also be built and operated in desert areas.
  • Stroke memory Power plants with rope winch lift can work on any terrain - too in the lowlands - built and operated. Stroke memory Power plants with Seilwindenhub can be large differences in height (z. B. shafts of mines) use.
  • Stroke memory Power plants with Seilwindenhub can completely or partially be built under the earth's surface or as a foundation be formed by buildings. 25, 26 You claim small areas and can z. B. built in any industrial area become. The consumption of scenic areas can be avoided.
  • Stroke memory Power plants with Seilwindenhub work environmentally friendly and low maintenance. For the construction only materials are needed, the pollutant-free can be recycled.
  • Hubspeicher power plants with Seilwindenhub can be built with technology available today. Winches are used today in a variety of ways. (eg: loading cranes, construction cranes, elevators, conveyor baskets in mines, cable cars, etc.). Port cranes 7) lift z. B. weights of 200 t to 50 m. This corresponds to a potential energy of approx. 30 kWh. If a 36 tonne basket is lowered 1,000 meters into a mine shaft, it can release the potential energy of 100 kWh. Existing plants can be expanded with slight modifications to Hubspeicherwerken. For new plants, the ability to store electrical energy can be constructively provided and thus the efficiency of power generation can be optimized.
  • The Winches can also be used to drive vehicles to go up or down on a roadway.
  • The Technique of the cable winch stroke can also be used in the lifting power plants become. This can be several winches by lowering the Floating body to be driven.
  • Hubspeicher power plants with cable winch lift are scalable, ie several sub-plants can be combined into storage systems with high storage capacity. Drawing 6 shows the principle of a Hubspeicher power plant with Seilwindenhub consisting of three memory modules. An example calculation illustrates the achievable storage capacities. The mass carriers have the shape of a cube with an edge length of 5 m, resulting in a volume of 125 m 3 . The mass carriers consist of rock or concrete with a density of approx. 3 t per m 3 . The total weight of a mass carrier is assumed to be 360 t.
  • The lifting of the mass carrier by 100 m can be achieved with today's crane technology 7) . The potential energy of a memory module is then: 360,000 kg × 100 m × 10 Ws / kg × m = 360,000,000 Ws 360,000,000 Ws / 3,600 Ws = 100,000 Wh = 100 kWh
  • The Base area of a module can be about 10 m × 6 m surface area to be built. On an area of only about 120 m × 100 m can 200 memory modules be housed. Such a memory can be a potential Energy in the size of approx. 20,000 kWh = 20 MWh take up. The example calculation illustrates that Hubspeicher power plants with Winch lift the capacity of pumped storage power plants reachable.
